Frequently asked questions
What is geofencing and how do retailers use it?
Geofencing creates a virtual boundary around a real-world location: a store, a shopping center, or a competitor’s parking lot. When a customer’s device enters, dwells in, or exits that boundary, Radar creates a location event that your team can configure to trigger any downstream action: a push notification, a loyalty prompt, a pickup alert, a staff workflow, or anything else your app supports. Retailers use Radar’s geofencing to power in-store app experiences, automate curbside pickup, run location-triggered marketing campaigns, and measure foot traffic attribution, all without building location infrastructure from scratch.
What is curbside pickup, and how does Radar improve the experience?
Curbside pickup allows customers to order online and collect their order from a designated spot outside the store without coming inside. The challenge for most brands is knowing exactly when a customer has arrived without relying on them to manually check in. Radar detects when a customer is approaching or has arrived at your store, then automatically triggers the right action on both ends: the customer's app surfaces pickup instructions, and your staff gets an alert to bring the order out. No manual check-ins, no "I'm here" button. The result is faster handoffs and a better experience for both the customer and your team.

Can Radar help drive more foot traffic to my stores?
Yes. Radar Engage lets you send timely, personalized messages to customers when they’re near one of your locations, near a competitor, or in a high-intent moment. Brands using Radar for nearby notifications have seen conversion rate lifts of 25 to 57% compared to generic campaigns. You can also use geofencing to power loyalty triggers and in-app promotions that activate the moment a customer walks through the door.
Can Radar help increase in-store purchase size?
Yes. Radar's location infrastructure enables Store Mode, an in-app experience that activates the moment a customer enters a store. Store Mode surfaces personalized product recommendations, loyalty rewards, and location-specific promotions at the exact moment customers are most likely to act on them. Users who engage with Store Mode convert at 2.5x the rate of those who don't, making it one of the highest-impact tools retailers have for driving in-store revenue through their existing app.
Does Radar protect against promotional fraud and location spoofing?
Yes. Radar Protect uses location signals to verify that promotional offers and high-demand product releases aren’t being abused by users masking or manipulating their real location. Radar detects GPS spoofing, VPN and proxy usage, and device tampering in real time, so your promotions reach real customers rather than bad actors gaming the system. For example, DICK'S uses Radar to keep high-demand sneaker releases fair, stopping location spoofers from jumping the queue and ensuring inventory goes to customers within a defined zip code.
Can Radar's address autocomplete be built into our checkout flow?
Yes. Radar's autocomplete API is designed to drop directly into checkout and account creation flows with minimal engineering lift. As a customer types, it surfaces accurate address suggestions, reducing keystrokes, preventing entry errors, and improving completion rates. It works across web and mobile and is used by retailers including DICK'S Sporting Goods, Michael's, Zappos, and more.
